Re: Autoheader @ interpolation

[Akim Demaille]

| Hi,
| I was trying to upgrade an old file when I stepped into this bug.
| Using AH_TOP to include a header into the template file resulted on:
| 
| couldn't parse /tmp/ah79k8w8/traces.pl: In string, @andrew now must be 
written as address@hidden at /tmp/ah79k8w8/traces.pl line 22, near "@andrew"
| 
| I have searched for this error:
| 
| http://perl.plover.com/at-error.html
| 
| It seems that autoheader is not parsing "@" to "\@" when passing the string 
to perl.

I have tried to reproduce the bug you are referring to, but it
passes.  Could you provide a configure.ac that exhibits the problem?

        * tests/tools.at (autoheader): Put randoms `@' to stress Perl.
